“…The TIP-δ method was tubularized incised-plate urethroplasty (TIPU) covered with a penile skin flap created immediately below the distal end of the neourethra as Gardikis et al, from our surgical team described before. 5,6 The technique used in mid-shaft hypospadias was tubularized island flap (TIF) in 12 patients, onlay island flap (OIF) in 5 and TIP-ελ in 27. TIP-ελ is the long TIP technique with covering by a second layer from a tunica vaginalis free graft as described by Voges et al 7 The operative technique for proximal hypospadias was TIF in 15 patients, OIF in 10 and TIP-ελ in 21.…”

BACKGROUND Hypospadias repair is a challenging type of urogenital reconstructive surgery for which different techniques are currently used. The purpose of this study is to determine the outcomes of distal, mid-shaft and proximal hypospadias repair using two new variations of tubularized incised plate (TIP) urethroplasty (TIP-δ and TIP-ελ) and to compare their complication rates with other already known operative techniques made from the same surgical team. METHODS This study included 269 boys with hypospadias. The preoperative meatal site was distal in 179 patients, mid-shaft in 44 and proximal in 46. The average age at the operation was 17 months. The technique applied in distal hypospadias was Mathieu in 77 patients, Snodgrass in 28 and (TIP)-δ in 74. The technique applied in mid-shaft hypospadias was a tubularized island flap (TIF) in 12 patients, onlay island flap (OIF) in 5 and TIP-ελ in 27. The operative technique for proximal hypospadias was TIF in 15 patients, OIF in 10 and TIP-ελ in 21. TIP-δ and TIP-ελ are two new variants of TIP operation that we have used in our clinic since 2010. Postoperative complications were recorded, and we compared the outcomes obtained by applying the techniques. RESULTS The use of TIP-δ in the distal hypospadias and long TIP-ελ in the mid-shaft and proximal hypospadias resulted in significantly fewer complications than the other surgical methods across all cases of hypospadias ( p <0.05). CONCLUSION The type of tissue used for neourethral coverage seems to play an important role in the outcome of hypospadias surgery.
